Guest butlersZ Posted July 17, 2003 Share Posted July 17, 2003 Hi, I have aquired a 283 block with the casting number 3959532. Can anyone tell me about this block such as when it was made. I plan to bore it to a 302 and put it in one of my Z's. Also, it has the "dip" in the bottom of the cylinder walls instead of the flat bottom, in case that helps with the years it was made. Correct me if I am wrong, but doesn't that signify that the block was made using the 327 tooling? There is another # on the block, CEOB00773, what does it mean?

Mike kZ Posted July 17, 2003 Share Posted July 17, 2003 It's a '64 replacement block. The CE is for replacement. http://www.mortec.com/castnum.htm Quote Link to comment Share on other sites More sharing options...
